Application filed February 28, rear. Serial No. 539,829.

To all whom it may concern:

Be it known that I, i E T. ANDERSON, a citizen of the United States, and resident oflButler, in the county of Butler and State of Pennsylvania, have invented a new and useful Improvement in Connecting Bars; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to connecting bars, andmore especially to such as areusedfor connecting the brake-levers of railway trucks, push-rods for brake-cylinders or other purposes. I

The object of my invention is to provide a bar or strut which is so reinforced as to provide a light but very rigid and durablebar capable of resistingthe bending and compressive strains to which such bars are subjected when use. 1

In the accompanying drawing Fig. l is a side view broken away of my improved connecting bar; Fig. 2 is a plan view of same; Fig. 3 is a section on the line 3-3, of Fig. 1; Fig. 4 is an enlarged section on the line M, Fig. 2; Fig. 5 is an end view, one-half of one of the clevis members being shown in section;.and Figs. 6, 7 and 8 are cross sections of modified forms of my invention.

The body portion 2 of my improved connecting bar is preferably made of steel, and for convenience of manufacture is formed from an ordinary rolled beam of an H or 1 section. The beam from which my improved connecting bar is made is illustrated in dotted lines, Fig. 4. Such a beam, by'a forging or pressing operation in suitable dies, is brought to the cross section indicated in sectional lines, Fig. 4, the flanges of the beam having been curved to form the substantially semi-circular portions 3 and l with the intervening longitudinally extending spaces or slots 5. The edges of said semicircular portions may meet, however, if desired. The web 6 of the beam connects these semi-circular portions 3 and 4 extending longitudinally and centrally of the bar, and act,

ing as a brace or connection between said semi-circular portions, and providing a very rigid and durable construction as a ainst to bending and compression strains;

The end-portions'of the bar are forged to form the clevis members 7, the web-portion of the beam being removedso as to present the slots 8 for the passage of the brake-lever or other art. Simultaneously with the forming-o theclevis member-s7, or subsequently thereto, the bolt or pin-holes 9 are formed, there being suflicient metal in the.

extends up close to the first bolt or pin-hole in the clevis-members, as clearly indicated in Figs. 2 and 3, which adds strength to the construction, and at the same time allowsample clearance for the movement of the levers contained within the slots 8 of the clevis-members.

lit is apparent that the cross-section of my improved connecting'bar may vary, and in Figs. 6, 7 and 8 l have shown various modifications, all of saidmodifications, however, containing the main feature of my invention, namely, the longitudinally extending web connectingtheoutside portions which are formed by the flanges of the beam, and

which may be of many difierent shapes.

What I claim is:

1. A connecting bar comprising a body portion formed of a beam with flanges and a connecting web-member, the upper and lower flanges at one side of said web-member being turned inwardly, and clevis members formed at the ends of .said body from the I flanges of said beam, said web member being removed at said clevis members. 7

2. A connecting-bar comprising abody member with inwardly extending portions, a

web-member extending longitudinally and centrally of said body, and; clevis-members formed at the ends of said body, said web member being removed at said clevis-memhers.

3. A member having oppositely disposed s. circular portions appreaching each other, a

connecting-bar; comprising a body- I 'web-member extending longitudinally and members formed at the ends of said body 10 centrally of said body-member, olevis-memfrom the flanges of said beam, the web-members formed at the ends of said body-memher being removed at said clevis-members her, said web-member being removed at said In testimony whereof, I, the said HARRY 5 clevis-members. T. ANDERSON, have hereunto set my hand.

4:. A connecting bar comprising a body- HARRY T. ANDERSON. portion formed of a beam with flanges and a. Witnesses: e central connecting web, the flanges being HARRY M. HAYs',

bent inwardly toward each other, elevis FLOYD E. DAVIS.
